Description

A kind of electric fan guard retaining ring

The utility model relates to a kind of securing means of electric fan guard, belongs to the improvement of household electric appliance.

At present, the front and back guard of overall plastic desk-top or pedestal fan on the market generally connects to tighten up with an overall plastic retaining ring and is one, the general employing of existing retaining ring is overall plastic one-body molded for the structure of fastening plate is arranged, its junction button adopts one-body molded or bonding or the ultrasonic welding mode is arranged on the retaining ring two ends, but the guard retaining ring of this structure is in transportation, reach in the handling process and use certain hour junction button fracture and damage easily later on, cause the inconvenience in the use and influence its working life, the retaining ring integrate shaped type structure mold cost height of this structure of while, manufacturing efficiency is low, the assembling of split-type structural is cumbersome, influence manufacturing efficiency, the retaining ring cost of these two kinds of structures is also corresponding higher.

The purpose of this utility model provide a kind of simple in structure, durable, assemble electric fan guard retaining ring simply and easily.

The utility model comprises retaining ring and junction button, wherein junction button comprises base and riser, L-shaped and the integrated punching moulding of base and riser, base is gone out the card of opening towards the end, riser is provided with the hole of passing for lock screw, position, retaining ring two end part has bayonet socket, and retaining ring and junction button pass through card---and the bayonet socket clamping is integral.

The utility model is owing to adopt retaining ring and junction button split-type structural and junction button to form with the metal sheet punching out, the making of junction button and simple with being linked and packed of retaining ring, can improve its manufacturing efficiency, help reducing cost, in use be not easy simultaneously fracture and damage, more durable, long service life, and, make outward appearance of the present utility model more beautiful, generous because jointing is provided with decorative cover.

Describe basic structure of the present utility model and basic principle in detail below in conjunction with accompanying drawing:

Fig. 1 is a structural representation of the present utility model;

Fig. 2 is the exploded view of each parts of the present utility model;

Fig. 3 is the A-A sectional view of the utility model junction button.

As shown in Figure 1-Figure 3, the utility model comprises retaining ring (1) and junction button (2), wherein junction button (2) comprises base (21) and riser (22), base (21) and the L-shaped and integrated punching moulding of riser (22), riser (22) is provided with the hole of passing for lock screw (23) (24), then go out the card (25) of opening on the base (21) towards the end, retaining ring (1) position, two end part then has bayonet socket (11), and the width of card (25) is slightly less than the width of bayonet socket (11), its length is then few with the length difference of bayonet socket (11), can very easily junction button (2) and retaining ring (1) clamping be integral by the clamping of card (25) like this with bayonet socket (11), simultaneously, for guaranteeing that further junction button (2) and retaining ring (1) clamping are firm, base (21) the bottom punching out one-tenth of junction button (2) matches with retaining ring (1) external frame and the slightly inwardly curved edge that can fasten retaining ring (1) bottom surface in both sides of the edge, and gone out a movable plate in the middle of the edge, after junction button (2) fastens retaining ring (1) bottom surface, this movable plate rollable packs tightly, and further plays the effect that tightens up.For making outward appearance of the present utility model more beautiful generous, retaining ring (1) is gone up junction button (2) position and is provided with decorative cover (3), and decorative cover (3) is enclosed in the inside with whole junction button (2).

Basic principle of the present utility model and operating procedure are: at first respectively with junction button (2) and retaining ring (1) by card (25)---bayonet socket (11) clamping is integral, again two junction buttons (2) are strained to the centre, first junction button (2) firmly is connected on the retaining ring (1), retaining ring (1) is tightened up and lock guard, behind tension retaining ring (1), lock screw (23) is passed in the hole of two junction buttons (2) and two junction buttons (2) are linked together, thereby play the effect of locking electric fan guard by nut.
